SPECIFICATION forming part of Letters Patent No. 775,897, dated November22, 1904. Application filed July 25, 190i. Serial No. 218,149. (Nomodel.)

To all whom, it may concern:

Be it known that I, J OSEF DEGEN, doctor of philosophy, a subject of theKing of Prussia, residing at Di'iren, and whose post-ofiice address isNo. 26 Hohenzollernstrasse, Diiren, Prussia, German Empire, haveinvented a new and useful Gorn-Protector,of which the following is aspecification.

This invention relates to rings used for the protection of corns and thelike; and its object is to remedy the drawbacks attendant upon the useof the well-known description of corn-rings composed of a ring of feltand a layer of plaster. Those corn-rings frequently cause inflammationof the skin, this drawback being chiefly due to the want of elasticityof the felt employed. It has been found that a sufiicient degree ofelasticity can be given to the ring by making it of the well-knownabsorbent cotton-wool used for surgical dressing purposes if care betaken that the fibers of the cottonwool, which, as is well known, hangtogether very loosely, do not altogether lose their connection orcohesion. It has been found that this can be effected in a satisfactorymanner by slightly coating both faces of the absorbent-cotton-wool ringwith a solution of gelatin, glue, or some well-known substitutes forthese binding agents. This solution penetrates a short depth into theabsorbent cotton- WOOl and binds the fibers, so that in this way astrengthening layer is produced on both faces of the ring, which insuresthe cohesion of the ring without afl'ecting its elasticity.

The essence of the invention thus consists in making the corn-ring outof surgical dressing-cotton or absorbent cotton-wool and inclosing itbetween binding layers by coating it on both faces with a solution ofgelatin,

glue, or the like binding matter. Experiments carried out on a largescale with rings formed according to this invention have given verysatisfactory results.

A ring according to this invention is illustrated by way of example inthe accompanying drawings, in which-- Figure 1 is a vertical section,and Fig. 2 a plan.

The ring a, made of surgical dressing-cotton or cotton-Wool, is providedwith upper and lower stiffening layers 6 Z), produced by a coating witha solution of gelatin or the like. 0 is a layer of plaster arranged asusual, and (l the strap for securing the layer of plaster to the ringand fastening the ring to the foot.

What I claim is-- V 1. ,As an improved article of manufacture acorn-protector comprising, in combination with the usual plaster andsecuring-strap, a ring made of surgical dressing-cotton and having bothfaces impregnated with an elastic binder, substantially as and for thepurpose stated.

2. As an improved article of manufacture a corn-protector comprising, incombination with the usual plaster and securing-strap, a ring made ofsurgical dressing-cotton and having both faces impregnated with gelatin,substantially as and for the purpose stated.

in testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
